Hi there,
I've have this exact same problem with my newly purcahsed Vive pro kit [and wireless adaptor].
The documentation that shipped with the equipment [attached] shows a maximum play area of 7x7m using 2x 2.0 base stations. However when using Steam VR for room setup, it allows no more than a 4x4 play pace, even when a larger area is traced out [attached].
This appears to be an ongoing issue, can we please have a clear response on how to set up a 7x7m playspace with 2x 2.0 Base Stations, as advertised?
Many thanks.
